With the aid of a tag, the user creates a seal which affects a certain area around it removing the soul of the opponents from their bodies. The souls are then sealed within the tag.

If someone comes in contact with the tag or removes it from its place, the souls will be released. The souls appear as ghosts near the one who touched the tag, and are only visible and audible to that person. The souls, however, have no initial memory of their past life.
